    Probably you haven't installed "mdadm" package on Stretch.
    Also it is generally a good idea to create a configuration file
    "/etc/mdadm/mdadm.conf" [1] on Stretch.
    You can use this command to create array configuration string from
    metadata on disks:
        # mdadm --examine --scan
    
    To check array status:
        # mdadm --detail /dev/md0
      
      
    
    
    [1] $ man 5 mdadm.conf

With kindest regards, Alexander.
